JAMES W. scorr, OF COLORADO SPRINGS, COLORADO.

FLUID-PRESSURE REGULATOR.

srncmrca'rron forming part of Letters Patent No. 762,767, dated June 14, 1904.

Application filed July 28, 1903. Serial Nol67,323. (No model.)

rado Springs, in the county of El Paso'and State of Colorado, have invented a new and Improved Fluid-Pressure Regulator, of which the following is a full, clear, and exact descrip- The invention rel ates to fluid-pressure regulators such as shown and described in the Letters Patent of 'the Unit-ed States No. 552,202, granted to me December 31, 1895.

The object of my present invent on is to provide a new and improved fluid-pressure regulator which is simple and durable in construction, exceedingly sensitive in the working of its diaphragm, and arranged to permit the diaphragm to expand and contract in both circular and diametrical directions to prevent buckling of the diaphragm and to allow upand-down movement without danger of the diaphragm bending unduly.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims. 1

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. v

Figure 1 is a sectional side'elevation'of the improvement on the line 1 1 of Fig. 2. Fig. 2is a reduced sectional plan view of the same on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of one of the sectors of the diaphragm-supporting disk; and Fig. 4 is a sectional side elevation of the joint of adjacent iiectors, the section being on the line 4 4 of Between the sections A. and NM a diaphragm-casing A is held in the usual manner a diaphragm B, connected by a stem C and cross-bar C with a valve D, adapted to be seated at its lower end-D on a valve-seat E, interposed between a fluid-pressure inlet A and an outlet A in the section A of the diaphragm-casingA. The valve D is also adapted to be seated with its inner upper portion 1) 5 on a valve-seat E, formed on the cylindrical extension E of the valve-seat E, the said ex-.

tension having ports E for the passage of the fluid and elongated apertures E for the free passage of the cross-bar C.

The stem C extends into the section A of the diaphragm-casing A and connectswith a carrier F, pressed on by a pressure-regulating spring G, adapted to be set to any desired tension by a manually-controlled setting device H of any approved construction, the pressure being indicated on a segment H by a pointer H controlled by the device H, as more fully described in the Letters Patent above referred to.

The non-fluid pressure face of the diaphragm B engages a support I, arranged within the section A, and this support is in the form of a disk made in sectors, each having its outer end provided at the under side with roundedolf lugs I, engaging bearings A formed on the casing-section A, to allow the sectors to swing up and down, the free or inner ends of the sectors resting on ball-bearings 'J, sup ported on the spring-supported carrier F.

The diaphragm B-is provided with annular concentric corrugations B and with radial corrugations B, and the face of the support I adjacent to the diaphragm is similarly corrugatedthat is, provided with annular concentric corrugations I and radial corrugations P-of which the latter are at'the joints of the sectors, as plainly indicated in Fig. 2, it being understood'that the corrugations of the diaphragm and.those of the supportI are in register with each other.

Now by the construction described the diaphragm B is free to expand and contract, both in a circular as well as me radial direction, thereby eliminating all tendency of the diaphragm to buckle or warp, at the same time increasing the life of the diaphragm. Furthermore, -by having the supporting-sectors hinged attheir outer ends and theirfree ends supported on ball-bearings held on a yieldingly-mounted "carrier, all undue friction is prevented and the support is exceedingly sensitively mounted to insure a perfect flexing of the diaphragm under varying pressure.

In order to prevent undue wear on the diaphragm, a cushion B is preferably arranged between the diaphragm and the corrugated support, as shown in Fig. 1, and this cushion 1 is formed of leather, felt,-asbestos,. or like elastic material. I

In order to allow using the valve D as a stop-valve, the following device is provided.

A bolt or rivet J connects the apertured top D of the valve l) with the conical end K of abutting with its other end on a block P,

engaged by a screw-rod Q, screwing in the nut Q, held in the sleeve L, the screw-rod Q extending through a stuffing-box N to the outside of the casing and carrying at its outer end a hand-wheel Q for turning the screw-rod to move the lower end thereof in engagement with the stem K to press the latter downward, and with it the valve D, until the latter is seated on the seats E and E, and is hence in a closed position and locked therein by the screw-rod Q. When the latter is out of engagement at its lower end with the stem K, as shown in Fig. 1, then the valve is free to move upward against the spring-pressed stem K, and when the tension of the spring exceeds the maximum pressure of the fluidpressure in the section A then the stem K is pressed downward by the spring 0, and thereby forces the valve D to its seats E and E to close the connection between the inlet A and the outlet A. Normally the screw-rod Q is held in an uppermost position to allow the valve D to yield to the pressure in the section A. The sliding motion of the stem K is limited by stop-pins K, secured on the stem K and extending through' elongated ilots L in the sleeve L, as plainly shown in Now from' the foregoing it will be seen that by-the operator screwing the screw-rod Q downward the. valve D can be positively moved to its seat and locked thereon, and hence it will be seen that by the arrangement described the device can be readily converted from a fluid-pressure-regulating valve into a combined stop-valve and fluid-pressure regulator.

Having thus described my invention, I claim as new and desire tosecure by Letters Patent- 1.
